Be it irnownthet 1, Jenna A. @ZEANE, a citizen of the United States,residing at Belfast, in the county of Waldo and State oi Maine, haveinvented new and useful Improvements in Nut-Locks, or which thefollowing is a specification.

This invention relates to an improvement in nut iocks.

in carrying out my invention it is my purpose to iplify and improve theexisting an; by producing nut lock formed .from a single strip orsuitable niateriai and. comprisinga bolt engaging body having anangularly disposed tongue, the said body at the juncture of the tongueand upon its upper face being formed with a V sheped groove, theopposite Walls of which being arranged at angles of forty-five degreeswhereby the tongue may be readiiy bent 'upon the body to permit of theangular walls contacting so that the said tongue will assume a positiveright angular-position with relation to the body.

It also my IKKPOSQ to provide a nut lock wmprising a mdy having boltengaging means and which, during the process of stamping is formed withan angular bendable tongue, said body, at the juncture of the tonguebeing formed with a groove which serves a guide upon which the tongue isbent and the gap provided by the groove be- ,ing suiiicientto permit ofthe nut moving thereover without contacting with the tongue when thesaid nut is screwed upon the bolt.

V ith the above and other objects iuview, the improvement resides in theconstruction, combination and arrangement of parts set forth in thefollowing specification and falling Within the scope of the appendedclaim.

In the drawings:

1g the enguiar at; with respect to In prociucing: any nut lock itungiitgca. suitabie me tilZB-ZEPGQ to operate upon a. strip ofcomparatively or: grade steel, produce therefrom the that body porticn'lof the lock, to form the with a cehtrel bolt receiving opening withinwhich extends a lug 2 that is adapted to e: e in a longitudinail e iiding groove :1 in the bolt 4, and to further form the body with alongitudinally extending angulariv disposed tongue 5, as well as to formthe had at the juncture of the tongue therewith with a sub.- stantialiyii-shaped were 6 that is disposed five degrees so that when the tongueis bent upon the body the walls oi. the reeve- I uun contact with eachother and .W en in such Contact the tongue 5 "will be arranged at aright angle with relation to the body.

The inner shoulder provided by groove l3. indicated, for distinction, bythe numeral over the gap provided by the said groove I and the punctureof the tongue 5 with the body, opposite the groove, is angular; that is,the tongue is not rounded from the body. This is permitted by thearrangement oi the bed upon which the Ciie worhsandie.

The arrangement of the groove (3 and the particular location thereof aredeemed the essential features of the present. invention. \Vere the. locknot provided with this groove and the metal employed in its constructionof any determined thickness, the same, whenbent at a right angle, wouldnecessarily contract upon its inner surface and draw or expand the metalat the outer corner bend. This would cause themetal to be )iled at theinner corner of the bend, so that an uninterrupted right angular surfacebetween the body and the tongue would not be produced. With metal of aco'mpara tively cheap grade "and which embodies a determined amount ofbrittleness the same cannot be bent at breakage. ,With spring metal thebent pora tendency to spring outward from the nut so tongue will notpositively engage with 'the surface of the said side and in no instancetively right angular tongue and body be assured for by theC(iltiilt'tlllg angular groove when my tongue is bent.

It is, of oourse. to be understood that ditt'erent washers are providedfor various as is provided -sizes and shapes of nuts, and from the above1t is thought that, the simplicity and advan of the a" right anglewithout also whereby the that. the

faces of the nsoaees tages of my structure will be apparent withoutfurther detailed description.

Having thus described ,the what, I claim is:

The herein described eonstruetion'of nut Locks formed in the process ofmanulaeture to provide a fiat body and a rectangular tongue arrangedangularly with respect to the body, said tongue and body, at thejuncture therebetween being, thickened in the said process ofmanufacture at the outer corner provided by the juncture of the saidtongue and body. the body having a bolt open ing provided with aninturned lug. and said lug being.arrangeil approximately central withrespect to the tongue. the body and tongue upon the outer face of thedevice being cut transversely and the walls provided by'the cut beingangular with, respect to each other, whereby when the said tongue isbenttoward the body, the said angular walls viltcontact to retain the tongueat a right angle with respect to the body, and thickened corner of thedevice will cltect in preventing the breakage or injury to the tonguewhen subjected to the impact of iorcein bending the said tongue towardthe body. and the tongue being of a greater length than the thickness ofthe nut which is adapted to be arranged upon -thc body,

In testimony whereof I aliix my signature in presence ot two witnesses.
